A Joint Sealing Compound must display good adhesion towards concrete and have the ability to withstand extension without cracking. It must also have a low susceptibility to flow during hot weather conditions. It should be durable and plastic, and at the time offer resistance to ingress of solid foreign matter. The filling up of joints with expansion joint filler itself is not enough to prevent the ingress of water. The top surface of the joints-construction, dummy as well as expansion joints are sealed with material which is waterproof as well as weather resistant.

        It has two grades such as CLEXODAM-SEAL GRADE-A & CLEXODAM-SEAL GRADE-B.

The joint compound is heated to temperature which will permit easy pouring into the expansion joint above the joint filler. This temperature should be well below that at which the joint sealing compound undergoes decomposition and should not exceed temperature as specified against each grade of sealing compounds.

CLEXODAM-SEAL is an ideal joint sealing compound having following properties-

§  It exhibits good adhesion to cement concrete.

§  It does not crack during expansion and contraction of slabs.

§  Its temperature susceptibility is low enough to prevent excessive flow during summer.

§  It is durable and plastic and does not allow any foreign material to penetrate into the joints

  CLEXODAM-SEAL GRADE A – 1834/1984

It is ideal hot pour sealing compound specially rubberized to withstand cracking. Besides having good adhesion to concrete it is also durable and is not affected by temperature changes. It has a working temperature of 175˚c-185˚c and a density of 1020 kg. Per cubic meter

CLEXODAM-SEAL GRADE B -1834/1984

It is unaffected by petrol spillage especially jet fuel. It is therefore recommended for use in garages, filling stations etc., where there is spillage of petrol, oil and grease. It has a working temperature of 155˚c-165˚c and a density of 1200 kg per cubic meter. On application of this product CLEXOBITU/JET-PMR is to see that primer has sufficiently dried prior to pouring of CLEXODAM-SEAL into the joint.

§  Every possible precaution should be taken to ensure that the joints are clean and free from debris and other foreign matter at the time of laying and during the curing process.

§  The primer is applied cold either by a spraying machine or by brush.(primers are inflammable and should not be place near a named flame)

§  The sealing compound should be heated to the working temperature in a suitable heater, and  transferred to a meter-pourer of suitable design, if available for pouring
